Insights
Patients with myasthenia gravis (MG) do not face higher COVID-19 risks. This study found no increased susceptibility or severity of coronavirus disease 2019 (COVID-19) in MG patients based on age or thymectomy status.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Coronavirus disease 2019 (COVID-19) is a global pandemic with significant mortality.
- Comorbidities can worsen COVID-19 outcomes.
- Myasthenia gravis (MG), a neuromuscular junction disorder, theoretically poses a risk for severe COVID-19 due to respiratory compromise.
Purpose of the Study:
- To investigate the pattern of COVID-19 infection in patients with myasthenia gravis.
- To assess if MG patients exhibit increased susceptibility or severity of COVID-19.
- To evaluate the influence of age, thymectomy status, and disease duration on COVID-19 outcomes in MG patients.
Main Methods:
- A prospective cohort study involving 150 patients with myasthenia gravis.
- Monitoring participants for six months for signs and symptoms of COVID-19 infection.
- Comparative analysis between COVID-19 infected MG patients and non-infected MG patients.
Main Results:
- No statistically significant difference in COVID-19 susceptibility was observed between MG patients and controls.
- COVID-19 severity in MG patients was not found to be increased based on age, duration of MG, or thymectomy status.
- Analysis did not reveal a correlation between MG clinical status and COVID-19 outcomes.
Conclusions:
- Myasthenia gravis does not appear to confer increased susceptibility or severity to COVID-19.
- Factors such as age, thymectomy status, and disease duration did not influence COVID-19 outcomes in the studied MG population.
- These findings suggest that MG patients may not require specific COVID-19 management adjustments beyond general recommendations.
Abstract:
Background: Coronavirus disease 2019 (COVID-19) is spreading rapidly and has affected millions of people worldwide. Comorbid diseases have complicated the course of infection and increased mortality. Myasthenia gravis (MG) affects the neuromuscular junctions (NMJs) and can compromise respiratory muscle action, leading to worse clinical outcomes in individuals infected with the COVID-19 theoretically. In this study, the aim is to assess the pattern of COVID-19 infection in patients with MG based on several factors. Methods: This was a prospective cohort study following 150 patients with MG over a six-month period. The patients were monitored for the development of signs and symptoms of the COVID-19 infection. Results: Comparison of the patients infected with COVID-19 with MG and those not infected was performed independently based on age, duration since MG diagnosis, status of thymectomy, and current clinical status of MG disease. Data analysis did not reveal increased susceptibility or increased severity of COVID-19 illness based the criteria assessed. Conclusion: COVID-19 related deaths and susceptibility were not related to age, thymectomy status, and disease duration in patients with MG.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
